Hi Sarge :wave:
..you must have sneaked in there as I was turning in!
I haven't put these Sunlite's through a barrage of exhaustive tests, per CPF standards, but I'll give you my initial impressions backed up by several months of intermittent use.
Sunlite's runtimes are based on dimming to 50% of initial brightness.
I use lithium primaries exclusively and haven't gone through a set on any of mine yet so I can't confirm the actual runtime.
I can tell you, that I've got at least 10-12 hours on my 2xAAA model and it shows no signs of dimming!
These lights are
current regulated and once you take it apart you will be blown away that they can fit everything in that tiny little head!
To summarize the general fit/finish of these lights: These are true "work lights".
Nothing fancy to look at but the specs are very high especially when compared to the cost.
You'll need to give them a little once-over with TLC to get them up to flashaholic standards. Krytox is strictly optional!
I first discoverd these on a Snap-On truck (yes, I'm a "toolaholic"!) and anyone that knows about Snap-On knows they only cater to top quality products.
They're designed for durability and high performance over what I would guess to be a very long lifetime.
Since these are specifically made for shirt pocket carry (SPC?) there is no lock-out on the switch.
I don't mind that one bit because I want instant activation when I reach for one.
I've never considered carrying one of these in a trouser pocket.
Not suitable in my opinion because that is what I consider true EDC territory and the competition there is fierce!
I keep the 100 lumen model in a pencil holder on a desk disguised amongst the various pens/pencils/sharpies.
So far its use has been mostly tactical for blinding/disorienting the unsuspecting victim. muwahahahaaa
The lights are very water-resistant and I was pleasantly surprised when I retrieved mine after a 48+ hour @ 16" depth, highly scientific "sink test" and discovered NO leakage. :thumbsup:
I use UV dies and especially LOVE their UV lights! ..true UV emissivity @ specific wavelengths because they are manufactured in house and quality controlled.
Hope that helps!
